Approved consistent with CDC acknowledgment that the study design limits the extent to which it can determine the impacts of uranium exposure on birth outcomes and child development. As such CDC commits to: a) making sure that its contractors set realistic expectations with its study participants, including ensuring that all recruitment materials (e.g., YouTube videos and presentations at meetings) are consistent with the study goal of Âimproving CDCÂs understanding of the relationship between exposures and health endpoints rather than quantifying risk, and b) clearly articulating the limitations of the study design and, accordingly, of its conclusions when disseminating the findings to its stakeholders (including other Federal agencies, Congress, and the Navajo Nation).

The Navajo Birth Cohort Study is the first prospective epidemiologic study of pregnancy and neonatal outcomes in a uranium-exposed population. The purpose of study is to quantify fetal risk from uranium exposure by recruiting Navajo mothers, assessing their uranium exposure at key developmental milestones, and following the children post-birth to evaluate any associations with birth defects or developmental delays. Additional research goals include assessing potential interactions with other heavy metals in the environment and determining activities and source contributions that lead to increased maternal/fetal uranium exposure. This will provide broad public health benefits for Navajo communities through outreach and education on the importance of prenatal care, environmental prenatal risks, and earlier assessment and referral for known developmental delays. Study partners include ATSDR, Univ. of New Mexico Community Environmental Health Program (UNM-CEHP), Navajo Area Indian Health Service (NAIHS), and Navajo Nation Division of Health (NNDOH).
